Figure 2

Circumferential and radial strain in respect to changes of left ventricular ejection fraction. The figure shows changes in circumferential and radial strain in respect to changes of left ventricular ejection fraction (EF) at rest and with dobutamine stress (10 and 20 μg/kg^-1/min^-1). Values expressed as mean with standard deviation. LV = left ventricle, EF = ejection fraction.
